The Light of the Two Trees did more than simply illuminate the land of the Valar, it conveyed a recognisable blessing and power on the inhabitants of the land. That blessing remained for a time even outside Aman, so that when the Valar and Ainur travelled to Middle-earth, it continued to shine from their faces. Even the Noldor, after they exiled themselves from Valinor, still showed the Light of Aman in their eyes for a time after their return to Middle-earth.
